nnnunomron To aziz'waom it may concern "Be it known that I, ADAM York, county and State of New York, have invented certain new and useful Improvesistsin making an annunciator having a minimum number of parts. This I accomplish by striking up the keeper,the support for'the armature support and the means for limiting the gravity element, which can be punched' from sheet metalin a minimum number of operations.

A further obj ect consists in so constructing the parts that thesame' will occupy the minimumf amount of space and w1thoutinterfering one with another whena plurality are used together.

\ Another object consists in producing an annunclator possess1ng,;1n addition to the above enumerated advantage, the quality of simplicity and cheapness of manufacture.

In the drawings Figure 1 is a rear elevation of four annunciators, showing how they are grouped in sets This figure also.

serves as an assembly view of an individual annunicator. Fig. 2 1s a rear view of the device'shown partly in section. Fig. is a side elevation. Fig. t is afrontview showing the indicating arrowfin front of the characters represent like parts in the difierpanel and the annunciator proper in dotted lines behind the panel Fig. 5 is a detail view of the frame and keeper showing the part which is struck up fromone piece by the die. I

Referring to the drawing in which like ent'views: 10 designates a support for the keeper 16. Itis to be understood that whereeverthe word keeper is used, whether in the descriptive part of the specification or in the claims, I ,refer tothat part of the struck up metal to which'the electro-magnet is secured or, as in this case, suspended. This is preferably made of stamped sheet iron. This support at the upper portion is provided with a tongue 11 and a groove 12.

The tongue registers with the adjoining element and serves to maintain the parts in proper alinement. I. g The frame is perforated at 13 forthere- Specification of Letters Patent.

ception of a screw or other, securing means 14. This screw 14: holds the and keeper to the :panel 15. Thekeeper is bent substantially at right angles to. the portion 10. v The keeper 16. has projecting down-. wardly from it two wings 17 and'18." These spaced from the support 15. The/purpose of this space will be hereinafter set forth. The wing 18 has. bent at ,rightangles toit two lugs 19 and 20.: Theselugs are'perforated and a pintle :21; extends there through. .This pintle has, fastened on one end thereof the-indicating arrow 22, and on the other -a gravity drop 23., The lug 19 There ears serve to limit the extreme posi-' tions of the gravity drop. Thedrop has a cut outportion 26' whose bottom contacts w ththe'ear 25 andpreventsfurther rotary.

inovementof. thedrop' in one direction (see 'A, Fig. 1), and a shoulder 27 on the opposite side serves to limit itsextreme'movement in the, oppositefdirection. The other win 17 has bentat right angles to it the lugs' 28 and 29. The lugsare perforated and support {the pintle 30 which carries the armature 31. stamped out of sheet metal' and is provided I with two" upwardly extending arms '32. See Figs. -1 and 2. These arms'are perforated and'through these perforations passes thepintleBO previously mentioned. One or both of these arms also serve to limit the movement of the armature in its movement I I Patented Oct. 20, 1914. Application fi1ed December 19, 19 11. SeriaLNo. 666,695. 1 Y

wings are so placed that' they are slightly am; has extending from it two cars 21 and 25. i

The armature is preferably from the'magnet, the same coming in contactwith the'wing 17 and thus preventing further movement of the armature about the I pintle 30. One of the arms 32 is extended upwardly and carries at its uppern end an ear 33; The. drop28 is normally held up by this ear'33 which engages the shoulder 34'. A leaf spring .35 is fastened to the armature ;by being bent over oneend thereor, as shown at36, and curvedatthe, otherend to contact withthe wing 17, as shown at I ably fastened to the keeper 16, as by the screw 39.

1 The operation of Sthe'device is aslfollows:

The parts are normally as shown atYA Fig.1. yWhen the circuit to the magnet is e'd y's'om ms ssfes he a P 1 t (not shown) the magnet 38' attracts the armature3l. This magnetlc attraction be ing great enough to overcome the tension of the spring 35, causes the armature to take" the position shown at B, Fig. 1. Meanwhile;

the lug 33 attached to arm 32 of the armature has become disengaged from the shoulder 34 of the gravity drop 23. When the drop, on account of its weight and position, falls it carries the arrow 22 to indicating position as show-n at B, Fig.1. Whenthe currentceases'to fiowthrough the magnet the spring forces the armature from themagnet to the position shown at A; Atter the indication is noticed, the attendant raises thezweightdO by suitableexternal means not shown-which engages'with the part 41, of

the gravity drop. The lug33 is oammed against the curved 'portion of'th'e drop and because of thewspning tension from spring 35 finally drops behind theshoulder 34, thus holding up the drop and maintaining the needle in vertical nomind icatingposition.

rigidly upon the panel 15 with only one,

screw l-l as affastening. rlinother feature is that the gravity drop 23, in either raised or lowered position, is so formed that it re mains substantially within the bounding, lines of the annunciator;

It isto be understood that while I prefer the construction herein specifically illus' trated and described the invention is not limited thereto, but may be. embodied in:

other forms without departure from its proper spirit and scope as defined bytheappended claims.
